All points fall within the mapped polygons. The number and distribution of vegetation plots was determined according to the USGS/NPS Vegetation Mapping protocols. The protocol suggests that each vegetation association should have been sampled at least three times in order to capture the naturally occurring variation within the park. If each of the identified formation-level vegetation types represented only one association in Gettysburg National Military Park and Eisenhower National Historic Site, the minimum number of plots needed would have been 41. This assumed that areas labeled with modified Anderson level II categories would not be sampled, and that for formations with less than three polygons, one plot would be placed in each polygon. However, it is more likely that some formations represent multiple associations, and that in several cases, multiple formations actually represent the same single association. Therefore, we estimated that 112 plots was the maximum number of plots needed to sufficiently capture the range of vegetation types based on our initial reconnaissance of the parks. One hundred and twelve polygons representing different aerial photograph signatures and formation-level vegetation types were then selected for sampling. Plot sampling was conducted from May through August 2004. The diversity of vegetation types was significantly less than originally estimated, and therefore, only 70 plots were sampled in total. Eight plots fell within the boundary of Eisenhower National Historic Site (GETT.46, GETT.47, GETT.64, GETT.65, GETT.66, GETT.67, GETT.68, AND GETT.69), and the remaining 62 plots were located in Gettysburg National Military Park. All vegetation types were sampled over a range of environmental variables. C:\NPS 6 Parks\NPS 6 parks GIS\FONE GIS\WPC data points\fone_veg_plots.shp.xml 20040830 Metadata imported.
